Answer 2

x=-4/12+9

x=-4/21

Ответ: -4/21

Answer 3

To solve the equation 9x + 12x + 4 = 0, you can combine like terms and then isolate x:

9x + 12x + 4 = 0

Combine like terms:

(9x + 12x) + 4 = 0 21x + 4 = 0

Now, subtract 4 from both sides of the equation to isolate the term with x:

21x + 4 - 4 = 0 - 4

21x = -4

Finally, divide both sides by 21 to solve for x:

(21x)/21 = (-4)/21

x = -4/21

So, the solution to the equation is:

x = -4/21
